Space Flight Laboratory (SFL) confirmed that six radio frequency geolocation microsatellites developed for HawkEye 360 of Herndon, Va., have successfully communicated with ground control. The HawkEye 360 Cluster 8 and 9 satellites were launched on April 7, 2024 at 7:16 pm EDT from Florida aboard the SpaceX Bandwagon-1 Rideshare.

The two new three-satellite clusters bring to 27 the total number of geolocation microsatellites developed by SFL for HawkEye 360, which integrated Cluster 8 at its own plant in Virginia under SFL’s Flex Production Program. For Cluster 9, which represents the next evolution and includes updated payload and platform features, SFL handled the entire process, including development, integration, and testing, at its Toronto facility.

“SFL is proud to play a key role in the development of HawkEye 360’s space assets as it continues to expand and enhance its unparalleled space-based RF data detection and analytics capabilities,” said SFL Director Dr. Robert E. Zee.

HawkEye 360 selected SFL to develop its satellites due to the importance of attitude control and formation flying by multiple spacecraft for accurate RF signal geolocation. SFL has innovated compact, low-cost formation-flying technology at a maturity and price point that no other small satellite developer can credibly offer.

SFL built the HawkEye 360 Pathfinder satellites on its 15-kg NEMO platform. All subsequent clusters have been developed on the larger 30-kg SFL DEFIANT bus.

The HawkEye 360 constellation detects, characterizes and geolocates RF signals for a variety of communications, navigation, and security applications. Clusters 8 and 9 were launched in mid-inclination orbits to increase coverage over the busiest maritime traffic corridors at mid-latitudes, including the Indo-Pacific region, according to HawkEye 360.
